Pelvic MRI for Rectal Cancer: Tips on Interpretation

Recorded September 14, 2021

This case-based, one-hour interactive session is targeted toward surgeons involved in a multidisciplinary approach to rectal cancer care. It serves as an introduction to rectal MRI and the various interpretative assessments made at initial staging. Through a guided discussion between a colorectal surgeon and GI radiologist, the participant will be led through several cases, examining how interpretation decisions are made at MR and how various factors, including technical and patient-based characteristics, may impact the level of confidence in an imaging assessment. The participant will have opportunities to ask questions in real time as the cases are reviewed. Specific teaching points will be emphasized that should set a solid foundation regarding Rectal MR imaging for the surgeon.
